| Abstract |
This study was carried out on the Friesian herd of Sakha Experimental station, Kafer El-Shiekh Governorate during the period from July 1989 to July 1990 to evaluate average daily gain and feed conversion of 30 locally born Friesian males fed on rations with or without flavomycin as follows:
GI= Control group, GII = received 30 mg flavomycin/head/day and GIII = received 45 mg flavomycin/head/day. Three animals in each group slaughtered to evaluate the carcass characteristics and meat quality. The main results could be summarized in the following:
1) At the first period (10-13 month of age) treatment increased the daily gain by 4.9% for GII and 3.7% for GIII than GI. But at the second period (14-16 month), GII and GIII scored higher daily gain by 17% and 8.74% than control group.
2) In the second period the treatment improved the efficiency of feed conversion by 24.7% in GII and 13.7% in GIII than GI.
3) Animal fed 45 mg flavomycin achieved the highest dressing percentage (68.7%) compared to GI (66.8%) and GII (64.6%).
4) The second group (GII) scored the highest bonless meat (78.8%) and the lowest bone percentage (19.5%) in the carcass compared to the other two groups. But the differences were not significant.
5) The physical and chemical traits of meat did not significantly affect the flavomycin treatment.
6) The use of 45 mg flavomycin caused a decrease in fiber diameter and an increase in densities which lead to a decrease in the connective tissues among the muscle fibers.
¯It could be concluded that fed freesia calves on rations containing 30 mg flavomycin improved growth rate, feed conversion and carcass traits during the period of 10-19 months of age.
